Aims and Scope
Agroforestry, the purposeful growing of trees and crops in interacting combinations, began to attain
prominence in the late 1970s, when the international scientific community embraced its potentials in the
tropics and recognized it as a practice in search of science. During the 1990s, the relevance of agroforestry
for solving problems related to deterioration of family farms, increased soil erosion, surface and ground
water pollution, and decreased biodiversity was recognized in the industrialized nations too. Thus,
agroforestry is now receiving increasing attention as a sustainable land-management option the world over
because of its ecological, economic, and social attributes. Consequently, the knowledge-base of
agroforestry is being expanded at a rapid rate as illustrated by the increasing number and quality of
scientific publications of various forms on different aspects of agroforestry.
Making full and efficient use of this upsurge in scientific agroforestry is both a challenge and an
opportunity to the agroforestry scientific community. In order to help prepare themselves better for facing
the challenge and seizing the opportunity, agoroforestry scientists need access to synthesized information
on multi-dimensional aspects of scientific agroforesty.
The aim of this new book-series, Advances in Agroforestry, is to offer state-of-the art synthesis of research
results and evaluations relating to different aspects of agroforestry. Its scope is broad enough to encompass
any and all aspects of agroforestry research and development. Contributions are welcome as well as
solicited from competent authors on any aspect of agroforestry. Volumes in the series will consist of
reference books, subject-specific monographs, peer-reviewed publications out of conferences,
comprehensive evaluations of specific projects, and other book-length compilations of scientific and
professional merit and relevance to the science and practice of agroforestry worldwide.

PREFACE
The primary objective of this book is to offer practical means for strengthening the
economics and policy dimension of the agroforestry discipline. This book, written
by the leading experts in economics and agroforestry, encompasses case studies
from Australia, China, Kenya, India, Indonesia, Malawi, Mexico, Micronesia,
Tanzania, United Kingdom, United States, Zambia, and Zimbabwe. The applied
economic methodologies encompass a wide variety of case studies including
enterprise/farm budget models through Faustmann models, Policy Analysis Matrix,
production function approach, risk assessment models, dynamic programming,
linear programming, meta-modeling, contingent valuation, attribute-based choice
experiments, econometric modeling, and institutional economic analysis. It is our
belief that these methodologies help agroforestry students and professionals conduct
rigorous assessment of economic and policy aspects of agroforestry systems and to
produce less biased and more credible information.
Furthermore, the economic and policy issues explored in the book – profitability,
environmental benefits, risk reduction, household constraints, rural development,
and institutional arrangements – are central to further agroforestry adoption in both
tropical and temperate regions.
All of the chapters in this volume were subject to rigorous peer review by at least
one other contributing author and one external reviewer. We would like to
acknowledge the indispensable collaboration of those who provided careful external
reviews: Ken Andrasko, Chris Andrew, Peter Boxall, Norman Breuer, Bill Hyde,
Tom Holmes, Sherry Larkin, Jagannadharao Matta, Venkatrao Nagubadi, Roz
Naylor, Thomas Randolph, Gerald Shively, Changyou Sun, Bo Jellesmark Thorsen,
and Yaoqi Zhang. All reviews were coordinated by the book editors.
We would like to take this opportunity to express our gratitude to all the authors
and co-authors of each chapter for their valuable contribution and timely response.
Special thanks are extended to Jensen Montambault for making the production of
this volume on a tight time schedule possible through editing, technical, and
formatting assistance. We are also grateful for additional formatting and indexing
assistance supplied by Terri Mashour, Troy Timko, and Fauzia Zamir. Generous in-
kind and direct support were provided by the University of Florida and the USDA
Forest Service. Finally, we would like to express our appreciation for the guidance
of the editors at Kluwer Academic Publishing, Helen Buitenkamp, Sandra Oomkes,
and Amber Tanghe-Neely.

An Overview
1. INTRODUCTION
Agroforestry, the deliberate integration of trees with agricultural crops and/or
livestock either simultaneously or sequentially on the same unit of land, has been an
established practice for centuries. Throughout the tropics and, to some extent,
temperate zones, farmers have a long tradition of retaining trees on their fields and
pastures, as well as growing crops or raising domestic animals in tree stands or
forests (Alavalapati & Nair, 2001; Gordon & Newman, 1997; Nair, 1989). In the
late 1970s, agroforestry attracted the attention of the international scientific and
development communities due to its potential for improving the environment and
livelihood of rural tropical communities. The agroforestry prospective increased
further during the 1990s as scientists and policy makers recognized the potential for
applying agroforestry systems (AFS) to problems such as soil erosion, rising
salinity, surface and ground water pollution, increasing greenhouse gases, and
biodiversity losses in temperate zones and developed economies. Financial viability
and attractiveness has also proven AFS an important land use alternative in various
settings throughout the world (Garrett, 1997), generating increased interest in this
sustainable land-use management practice with potential environmental and
socioeconomic benefits.
Research over the past two decades has focused on exploring the biophysical and
ecological aspects of agroforestry with a limited emphasis on social aspects of
agroforestry, especially economics, policy analysis, and valuation of associated
environmental services (Mercer & Miller, 1998). Concern over adoption rates has
highlighted the importance of integrating socioeconomic elements into traditional
biophysical agroforestry research (Nair, 1998; Rochelau, 1998). As a result, there is
a growing interest and need for enhancing economic and policy research among
